7 window releasedly, Referring to the drawings, which are mere- 00 closed a window frame with a French or casement type of window, altho it is understood that the same arrangement can be made to apply to doors and door frames as well. The window frame is des gnated broadly A and designed to lit the opening C in this frame is a \VilKlOW sash of approved design an d construction hinged as at C so to be capable of swinging in a horizontal plane upon said hinges. T he under edge of the window is designed to be spaced above the threshold orstool E of the window frame which projects out wardly of the exterior face of the window fran'ie, being surmounted upon a window sill B in the usual manner. here is thus provided the space M between the lower edge of the window 10 and the adjacent threshold bead D secured on the threshold flush with the metal bracket formed angle-iron in shape, has its arm 17 secured by suitable fasteners 18 into inside face of the window 10 when the latter is closed. The head. D extends transversely of the opening C of the frame and has a forward downwardly inclined wall 21 disposed along a midposition of the threshold E. Formed upon the underside or under edge of the window 10 is a groove 15 and a sheet this groove so that its other arm 16 extends at right angles in depending relation from the arm 17 it will be seen that the arm 16 projects below the bottom plane of the groove 15*, and that the edge of the bracket in the notch is spaced away from the exterior wall of the groove 15 to provide between itself and the said notch wall a slit 15. Formed transversely of the bead D is a narrow slit 20 shown in Figure 4 and in this slit is designed to slide the depending arm 16 of the bracket as the window sash 10 moves from closed or open position or Vice versa. 1

I will now describe the Weatherstrip which I have designed. It is formed from sheet metal preferably an d consists of the elongated plate 12 made of a length to extend across the full width of the window frame A and has a right angular top offset 13 terminating in an angular flange 14 extending the full length of the Weatherstrip. This Weatherstrip plate 12 is designed to rest with its bottom edge upon the window sill B, being held against displacement from the threshold thereof by any suitable means. I prefer to secure a fastener or wood screw 19 in a manner to pass thru the weather strip plate 12, and be secured into the threshold, the plate being loosely mounted upon this screw so as to have play enough to hingedly swing to avertical operative position shown in Figure 3 to an inclined inoperative position shown in Figure 1.

It will be seen from Figure 1 that when the Weatherstrip inclines in inoperative position that plate 12 rests upon the forwardly inclined surface 11 of the forward end of the threshold E, with its offset 13 projecting over the stool and with its marginal flange 14 insans clining in flatcontact with the inclined wall 21 of the bead D. In this position the weatherstrip is supported on abias with no part of its makeup projecting above the plane of the bead D. The window sash 10 has been open to enable this weather-strip to occupy this po sit-ion.

When it is now desired to close the window to bar the frame opening, the window sash 10 is moved on its hinges and brought into position over the threshold E of the frame A. From Figure 2 it will be seen that the depending arm 16 of the bracket will be free to ride in slit 26 of the bead D. Due to the fact that the flange 14: of the bead closes the slit 20, as shown in Figure 1 the arm 16 will engage this flange, push the same forwardly, as it rides thru the slit 20, thus tilting the Weatherstrip outwardly and upwardly and then makes flange 14; of the plate 12 of the Weatherstrip enter the groove of the window sash, whence the flange begins to position itself inslit 15 of this groove, while the Weatherstrip is about to assume the vertical operative position shown in Fig. 3.

In this vertical position of the weatherstrip it will be observed that plate 12 bridges the space between sill and the under edge of the sash so no air, rain or atmospherecan gain access into the room. In forcing this Weatherstrip to assume a vertical position it makes joint with the sash with a press fit, so that the offset 13 engages the under edge of the sash to enable the upstanding flange 14 to pro ect into the groove 15 of the sash; it will thus be seen that the reentrant angle of the Weatherstrip provides a double check against the admission of the elements into the room as even if it gets thru between offset 13 and the adjacent surface of the sash it would have to pass upwardly between flange 1 1 and the adjacent wall of the groove. The flange 14 is preferably disposed at an angle slightly less than a rightangle where it joins the offset 13 of the Weatherstrip so with all parts as shown in Figure 8 the flange makes a press fit with the mentioned wall of the groove, thus effectively excluding Wind, rain and the like.

hen the sash 10 is moved to open position, there is room in the slit 15 of the groove for the flange 14 to work itself loose as shown in Figure 2, so as the sash recedes from the flange and plate 12 flange 14 leaves the sash groove and under influence of gravity the Weatherstrip falls down upon the threshold and bead and is idle again as shown in Fig ure 1. From the foregoing it will be seen that the Weatherstrip has a floating connection whereby it can open and close, opening to vertical position when the sash closes and closing to inclined or biased position when the sash opens.

I do not mean to restrict myself to the exact details of construction disclosed in the draw ings but intend to cover all variations falling within the purview of the appended claim.

What I claim and seek protection on is as follows In combination with a rabbeted casement or outside door frame, a sash or door hingedly mounted on said frame, in inswinging position, a groove in the lower edge of the bottom rail of the sash or door and a metal bracket secured to the bottom of the groove with its depending arm extending down below the bottom of the sash or door,amovable weatherstrip device which consists of-a longitudinal sheet metal plate having a rightangular U marginal flange with a reentrant outstruck marginal strip formed integrally upon the flange at a slight acute angle, extending the full distance between the jambs and retained in place by resting against the rabbets of 23 the ainbs with the lower edge of the plate when in inoperative position and with the fiat surface of the plate when in operative posi- I tion forming a fius'h surface with the outside face of the bottomrail of the sash or door, a 25 horizontal contact with the lower edge of the sash or door and a. vertical contact with the outer vertical wall of the groove in the lower edge of the bottom rail of the sash or door, when sash or door is closed. In witness whereof he has hereunder set his hand this twenty-third day of March, 1929.
